You have to add all the money up then subtract it by the following money you earned.

Step-by-step explanation:

45.35+45.25= 90.5

1.39x75=104.25

0.68x8=5.44

68.72x2=137.44

1.85x37=68.45

0.13x900=117

52.85x12=634.2

52.85x2=105.7

19.49x3=58.47

2750-1321.45=1428.55

(the number 1321.45 came from everything added together, which i then subtracted from 2750 to get 1428.55 as your remaining balance.

explanation:

We have been given a number 5.78. We are asked to choose the correct statement which shows that 5.78 is a rational number.

Upon looking at our given choices, we can see that only option A is the correct choice as it has repeating digits (78) after decimal.

We know that a number with repeating decimals can be written as a fraction, therefore, option D is the correct choice.

which is faster: drive a car at a rate of 40 kilometers per hour or drive a car at a rate of 15 meters per second

Answers

Answer:

Step-by-step explanation:

Let's convert one of these measurements so that both measurements have the same units.  15 m/sec is equivalent to 0.015 km/sec, which in turn is equivalent to

0.015     km      3600 sec  

--------- --------  ----------------- = 54 km/hr

    1        sec       1 hr

This latter result (54 km/hr) is faster than (40 km/hr).

15 meters per second is equivalent to 54 kilometres per hour.

The answer is D, or (2, -2).

Explanation: The angles that would make up the top left and right corners of the parallelogram would be (4,0) and (2,0). Because (0, -2) is the bottom left angle, to make this shape a full parallelogram, the y-coordinate of the other angle would have to also be -2, and it would have to be to the right of the origin so the figure does not look sloppy. To add on to this, none of the given x-coordinates are negative, so the fourth point should not have a negative x-coordinate. That would instantly get rid of A, B, and C. Therefore, your answer would be D, or (0, -2).

Answer:

  √689 ≈ 26.2 leagues

Step-by-step explanation:

For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.

Pythagorean relation

The Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...

  c² = a² +b²

Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.

  c = √(a² +b²)

Application to distance

The horizontal distance between the points is the difference of their x-coordinates:

  a = x2 -x1 = 2 -(-18) = 20

The vertical distance between the points is the difference of their y-coordinates:

  b = y2 -y1 = -10 -7 = -17

When we square these numbers, we find their signs to be irrelevant.

  c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689

  c ≈ 26.249

The distance between the given points is about 26.2 leagues.

Sqr root 689 should be the answer

A square pyramid on top of a rectangular prism. The rectangular prism has a length of 4 meters, width of 4 meters, and height of 4 meters. The square pyramid has triangular sides that have a height of 3 meters and side length of 5 meters. Compare the surface area of the composite figure to the surface area to the combined surface areas of the figures if they were separated. The composite surface area would be the surface area of the rectangular prism plus the surface area of the square pyramid considered separately.

Answer:

4 miles per hour

Step-by-step explanation:

Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.

Proportion

First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.

This creates the proportion [tex]\frac{12miles}{3hours}[/tex]

So, the rate we are given is 12/3.

Unit Rate

To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.

12/3 equals 43/3 equals 1

So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.

Graph

Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

4 miles per hour bc that's what the answer is
